Seven-Day Summary: 'Megamind' Drops But Stops 'Unstoppable'

Despite an abnormally large week-to-week decline, Megamind managed to hold off Unstoppable to top the box office for the second straight week. The week's other new releases, Skyline and Morning Glory, had middling grosses, while holdover Due Date plummeted. Overall box office was down around 14 percent from last year, when 2012 led with a massive $81.7 million.

Unstoppable cruised in to second place with $28.9 million in its first week. While the gross was off from The Taking of Pelham 1 2 3 ($32 million), it was about even with Man on Fire ($29.2 million). Unstoppable also had the distinction of finishing in first place on five out of the seven days this week, though it lagged behind Megamind on Saturday and Sunday.

Due Date fell a rough 54 percent to $20 million to bring its total to $63.5 million. This was much worse than The Hangover's 25 percent second week drop, and Due Date has made about half as much through its first two weeks.

Skyline earned $14.2 million in its first week, which was lower than The Fourth Kind's $15.8 million. It's also way off from the Strause Brothers' previous movie, Aliens Vs. Predator—Requiem, which made $28.2 million in its first seven days (though that was during the much more lucrative week between Christmas and New Years).

Morning Glory rounded out the Top Five this week, grossed $12 million for a nine-day total of $14.6 million. This was down from Definitely, Maybe but about even, attendance-wise, with Little Black Book.

Tyler Perry's For Colored Girls got crushed in its second week, falling 67 percent to just under $8 million. That's the worst drop ever for Perry, whose movies are already known for being incredibly front-loaded. With a two-week total of $32.1 million, For Colored Girls won't reach Precious's $47.6 million and will be Perry's lowest-grossing movie since The Family That Preys.
